Patent GB-758602-A (GB)
Title: Improvements in or relating to preparation of metal powders
Inventor: WHALEY THOMAS PATRICK
IPC: B22F9/20
Filed: 1954-07-12
Abstract: Metal powders are prepared by reducing at least one metal compound, other than an alkali metal compound, with one or more finely divided alkali metals suspended in an inert liquid medium. The metal compound is preferably a halide of the required metal and the inert medium may be benzene, xylene, toluene, gasolene, kerosene, mineral oil, isoparaffin mixtures, n-octane and n-decane.  Up to 2 per cent of a dispersing agent, e.g. a fatty acid, activated carbon, charcoal or carbon black, is preferably added to the dispersion.  The process is preferably performed under an inert atmosphere and the metal powder may be recovered from the reaction mixture by filtering or centrifuging after treating with an alcohol and water to "kill" any excess alkali metal.  The preparation of Fe, Zn, Cu, Ag, Cr, Co, Cd, Sn, Mn, Ni, Mo, Ag powders and of the powders of Cu-Zn, Fe-Cr, Ag-Cu, Cu-Sn, Sn-Zn alloys, by the simultaneous reduction of two compounds, is described.  Specification 719,835 is referred to.

Title: Method for Controlling the Carbon Content in and/or the Temperature of the Molten Steel in the Refining Process of the Steel
IPC: C21C5/30
Filed: 1966-05-09
Abstract: 1,156,722. Controlling oxygen steelmaking. SUMITOMO METAL INDUSTRIES Ltd. May 9, 1966 [May 13, 1965; Nov. 27, 1965], No.20398/66. Heading C7D. The steelmaking process is considered to take place in three stages, in the first of which decarburization rate is related to initial temperature and initial silicon content of the metal, in the second of which it is determined by rate of oxygen supply, and in the third it is determined by the remaining carbon content of the bath. A mathematical relationship between the decarburizing rate in the three stages is developed, so that once the various constants have been determined by experience the refining time necessary to produce any desired final carbon content can be calculated and blowing stopped at the appropriate moment. In a modification, the calculation is based not on the initial carbon content of the bath, but on the decarburizing rate as determined at a known point in the first blowing period. To obtain a more accurate end-point, the calculations may be revised as the refining proceeds, on the basis of the deviation between predicted and experimentally determined decarburizing rates or bath carbon contents. In a further modification the calculation is based on the discovery that decarburization rate in the first period can be regarded as a function of time. It is stated that blowing time to attain a desired final temperature may be determined in the same way as for carbon content.

Title: Self-tuning radio receivers
IPC: H03J3/00
Filed: 1963-05-24
Abstract: 1,019,336. Automatic tuning arrangements; remote control of radio receivers. STANDARD TELEPHONES & CABLES Ltd. May 24, 1963 [May 29, 1962], No. 20843/63. Headings H3P and H3Q.  In a radio receiver the tuning of which is automatically swept electronically over a tuning range, the sweeping rate is reduced whenever a signal is intercepted. The local oscillator 8 is tuned by means of a semiconductor voltage variable capacitor 21, to which a saw-tooth voltage is applied from a generator comprising capacitor 17 and gasdischarge tube 18, which are fed from the B+ + line via a normally-conductive valve 16. When a signal carrier is intercepted during a sweep, detector 14 coupled to the I.F. amplifier generates a negative voltage which biases the valve 16 to cut-off. Capacitor 17 and tube 18 are then fed only over resistor 25, which is of high value, the sweeping speed being correspondingly reduced until the sweeping has passed the intercepted signal, whereupon valve 16 becomes conductive again and the original speed of sweeping is resumed. A limiter discriminator 15 is also fed from the I.F. amplifier and its output may be introduced in series with that of the saw-tooth generator by means of a manual switch 27: in this way, when a desired signal is reached it can be held indefinitely, since the output of the discriminator swamps that of the saw-tooth generator. A further manual switch 28 enables the tuning to be controlled manually by means of a potentiometer 31. The tuning point is indicated in each case by means of a meter 32. The tuning control voltage may also be used to tune other R.F. circuits of the receiver by incorporating voltage variable capacitors in them (Fig. 4, not shown). It is stated that the arrangement lends itself to remote control.

IPC: B21F31/00
Filed: 1924-09-10
Abstract: 221,815. Bek, E. G. Sept. 10, 1923, [Convention date]. Drawings to Specification. Chains; wire fabrics.-Chains, and ringmesh fabrics of German silver, tombak, alpacca, silver, gold, &c., are soldered by electrolytically depositing one or more layers each containing two or more metals on the chain or fabric under such conditions as regards the relative dissociation of the electrolytes employed, attraction between the metals, and temperature, as to deposit the metals in the proportions of a soldering alloy and homogenizing the alloy and soldering the joints by a subsequent heat treatment. The different metals, especally silver, gold, zinc, cadmium, tin and copper are deposited simultaneously by the use of double salts, for example cyanides, or by the addition of salts capable of forming complex ions, by the selection of the metals so that their deposits form solid solutions or chemical compounds, for example silver and cadmium or silver and zinc, and by selecting the temperature for ejecting the deposit within the quantitative proportions for solid soldering. The melting of the metallic layers and the filling of the joints with the molten metal is effected by a short first heating, and the complete alloying of the deposited metals and an intimate connection with the surfaces at the joints is then effected by a heating of relatively long duration below the melting- point, for example by slow cooling. Suitable soldering-alloys for German silver are 70 per cent silver and 30 per cent cadmium or zinc; and 65 per cent silver, 5 per cent copper and 30 per cent cadmium. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the deposition of superimposed layers of single metals. This subject-matter does not appear in the Specification as accepted.
